Abstract

Background: Sleep problems are known as risk factors for depression and anxiety, but research on this subject with commercial pilots is limited. This study aimed to explore the effects of sleep problems on depressive and anxiety symptoms among Chinese commercial pilots. Methods: Adults who participated in the baseline assessment of the Civil Aviation Health Cohort of China between December 2022 and March 2023 formed the study sample. Depressive and anxiety symptoms and sleep quality were assessed using standardized scales. Sleep duration was measured with standardized questions. Logistic regression and restricted cubic splines (RCSs) were used to analyze the association between sleep problems and depression/anxiety symptoms. Results: A total of 7055 pilots were included in this study. The overall prevalence of depression and anxiety among pilots was 23.3% (n = 1642; 95% confidence interval [CI] = 22.3%–24.3%) and 17.0% (n = 1196; 95% CI = 16.1–17.8%), respectively. Logistic regression analyses revealed that short sleep duration (<7 h) was significantly associated with a higher risk of depression (odds ratio [OR] = 2.491; p < 0.001) and anxiety (OR = 2.555; p < 0.001), while poor sleep quality was also associated with a higher risk of depression (OR = 7.297; p < 0.001) and anxiety (OR = 7.469; p < 0.001). After adjusting for confounders, there was an inverse, J‐shaped nonlinear relationship between sleep duration and both depression (inflection point: 7.64 h) and anxiety (inflection point: 7.48 h). Similarly, a J‐shaped nonlinear relationship was found between sleep quality and depression/anxiety with an inflection point of Pittsburgh Sleep Quality Index (PSQI) = 4 points for both. The major limitation of the study was that causal relationships between variables could not be inferred due to the cross‐sectional study design. Conclusion: This study found that depression and anxiety were common among Chinese commercial pilots. Insufficient length and poor quality of sleep were associated with an increased risk of depression and anxiety. Implementing targeted strategies to improve sleep patterns is crucial for reducing the risk of depression and anxiety in this population. [ABSTRACT FROM AUTHOR]

Abstract

Background: Depressive symptoms commonly co‐occur with cognitive decline in older adults. However, prospective interrelationships between different cognitive function domains and depressive symptoms are not well understood. This study evaluated prospective interrelationships between depressive symptoms and cognitive functioning components among individuals aged 50 years or older from a perspective of network analysis. Method: Longitudinal data from the English Longitudinal Study of Aging were analyzed. Depressive symptoms were measured with the eight‐item Center for Epidemiologic Studies Short–Depression Scale. Cognitive functions assessed included memory, orientation, and executive function. Contemporaneous network analyses were conducted using mixed graphical model, while a temporal network model was assessed using cross‐lagged panel network model. To identify important predictors and outcomes, centrality indices, including expected influence, out‐expected influence, and in‐expected influence, were calculated. Results: A total of 6,433 older adults were included in the network analysis. Baseline "Not enjoy life" (CESD‐6) was negatively associated with executive function at the follow‐up assessment. Moreover, improvements in "Everything was an effort" (CESD‐2) and "Loneliness" (CESD‐5) were related to less future decline of executive function and memory ability. Furthermore, analyses suggested targeting "Lack of happiness" (CESD‐4) could be useful in reducing the co‐occurrence of depression and cognitive decline among older adults. Conclusions: This network analysis study highlighted dynamic interrelationships between depressive symptoms and cognitive decline in older adults. Findings suggest that interventions targeting specific depressive symptoms may have the potential to alleviate declines in executive function and memory for this population. [ABSTRACT FROM AUTHOR]

33. Bipolar disorder and oxidative stress: A bibliometric perspective.

Abstract

Objective: Accumulating evidence indicates that oxidative stress and the disruption of antioxidant defenses play an important role in the neurobiology of bipolar disorder (BD). Studies have found that increased oxidative stress may be associated with cell apoptosis and neuronal damage in BD patients. Hence, this study explored the research field related to BD and oxidative stress from a bibliometrics perspective. Methods: Literature search and relevant data retrieval based on the Web of Sciences Core Collection (WoSCC). R software (version 4.2.2), VOSviewer software (version 1.6.18), and CiteSpace (version 6.1.6) were used in this bibliometric analysis. Results: A total of 2081 publications related to BD and oxidative stress were published between 1986 and 2024. Bipolar Disorders was the journal that had the most publications in this area (72; 3.46%; IF = 5.9), while the United States (1285; 61.7%) and the University of Toronto (377; 18.1%) were the most productive country and institution, respectively. Apart from "oxidative stress" and "bipolar disorder," the most frequently used keywords were "schizophrenia," "prefrontal cortex," and "nitric oxide." Conclusions: The growing number of publications related to BD and oxidative stress in recent years highlights the importance of this research field. Hot topics in research related to BD and oxidative stress included animal experiments and molecular mechanisms, psychiatric‐related inflammation and biomarkers, neurodegenerative diseases, and metabolism. Furthermore, the biological mechanisms of BD, particularly biomarkers and inflammation, may be the emerging research priority area in the future. [ABSTRACT FROM AUTHOR]
